need for transparency, including the development of data on performance through self-reporting and verification to check the reliability of reported data, both through state verification systems and, as a less formal and costly alternative, in the form of external checks from other states and nongovernmental scientific interest groups. Second, Chayes proposed informal dispute settlement measures, suggesting compulsory conciliation that would result in nonbinding recommendations. This would ensure that conciliation efforts would be able to address a broad range of disputes, while maintaining principles of sovereignty by not forcing parties to accept the decisions reached. Third, deficits in technical and bureaucratic capability and financial resources can be healed through treaty provisions that expressly provide for technical assistance to those states that are incapable of compliance due to these domestic handicaps. Fourth, Chayes combined the elements of transparency, dispute settlement, and capacity building into a broader process of “jawboning” – the effort to persuade the violator to change its ways. This can be accomplished through discourse among the parties, the treaty organization, and the international community. Chayes argued that in an international system that is increasingly interdependent, states no longer have the freedom to act independently, but instead must submit to the pressures of international regulation. He thereby cites Robert D. Putnam “The sanction for violating [the norms and expectations generated by this network] is not penal, but exclusion from the network of solidarity and cooperation.” Throughout the book, Chayes stressed the importance of the international legal process in creating and sustaining regulatory treaties, noting how the need for improving compliance can be accomplished by cooperative problem-solving by international society. Legacy In 1996 he received the Peace Advocacy Award, with his wife, Antonia Handler Chayes, from the Massachusetts chapter of the Lawyers Alliance for World Security. In 1999-2000, Professor Chayes led a team of lawyers suing Slobodan Milošević in the U.S. Courts for genocide in Kosovo, and helped investigate corruption in Bosnia. He continued to work on international environmental law, teach, and serve on the Harvard interdisciplinary group on climate change. In 1999 he received the Harvard Law School Association Award (HLSA) recognizing his service as an "inspirational teacher and distinguished scholar, advocate for the rights of sovereign nations and the protection of the global environment, [and] beloved mentor to generations of Harvard Law students." The Law School celebrated his career with two days of panels and events concerning issues in international
